Selectively disabling A2DP - General Questions and Answers

Does anyone know a way to selectively or situationally disable A2DP? Tasker doesn't do it natively, and I haven't found an app or plugin to do it.
Here's the situation. I do not have bluetooth in my car. I run a Note 2 dock with integrated audio output running to my car's aux in. I have bluetooth headphones that I run constantly for media and handsfree. The problem is that when I plug into the dock, the media still tries to play over the headset instead of the dock output. Turning off the headset takes away handsfree, and it's too cumbersome to enable and disable A2DP through the bluetooth settings every time.

[Q] Bluetooth Headset Problem

I want to use Spype on my G Tablet - bought myself a bluetooth headset. I can connect no problem (can even toggle it on and off with the home screen button application) it beeps indicating the connection.
But when I do calls I doesn't use the mic and speaker of the headset. Matter of fact it seems like it messed up with my audio setting because my built-in speakers don't seem to work anymore.
Any thoughts?
Sometimes I have the same issue. If you want speakers back, try disconnecting from the Bluetooth device. If that doesn't fix it, just reboot. I just posted another comment about the impossibility to use a bluetooth headset, not just for output, but for audio input also. I guess this is because there's no HSP or HFP bluetooth profiles implemented on the g tablet, just a2dp, which is why it just can stream audio to an output device, like a bluetooth stereo headset or car audio. BTW, I discovered this when trying to achieve exactly what you tried to do, making calls using Skype.

[Q] How to disable internal speakers when connected to Bluetooth device?

When connected to a bluetooth device in car mode, I'd like to force all audio to the car bluetooth speakers and mute the internal speakers. Problem is, I don't see a mechanism to mute the internal speakers while not affecting the bluetooth volume in either Llama or Tasker. Does anyone know how this could be done or a Tasker/Locale plugin that has this functionality?

[Q] Bluetooth device management?

Do you know of any application that manages your bluetooth connections?
Here's what I'm talking about, I have bluetooth headphones, several speakers and my car that all are connected to my phone and I'm having several small issues.
- As soon as I turn on bluetooth it tries to automatically tries to connect to these certain speakers, I don't want that and don't know how to stop it.
- If I'm in my car, my phone connected to my car for calls and I'm listening to music through the headphone jack but it will automatically connect to a set of bluetooth speakers in my home when get home and pull into the driveway. So music will play through those speakers instead of my headphone jack. I obviously don't want that either.
-Titanium Backup never restores my bluetooth connection either so if there is an application that can save those too that would be helpful.

Is it capable of connecting bluetooth to multiple phone+media devices?

I can't find a way to have both my headset and car stereo connected at the same time without changing the bluetooth profiles in settings. Samsung s8 can do this automatically/natively. both bluetooth devices show connected for phone and media audio.
I use a bluetooth headset on my oneplus 6 (trialing it) during working hours for calls and music.. when i get in my car, I sometimes make calls on my headset... but in between calls, I want to listen to music on my car stereo. That's fine.... IF i remove media audio bluetooth profile from my headset first...
But wait..... Sometimes I want to transfer the call from my headset to my car stereo, and/or vice versa. I don't want to change the Bluetooth profile manually every single time i want to use a different device which I have been having to do.
Pretty please can you try connect your nex to 2 devices that have phone and media capabilities and see if you can connect them both at the same time? If so... try and switch calls between the 2 without changing any settings in the bluetooth? Will you take a screenshot of the bluetooth settings page once they are connected too? I appreciate your time.
Only Samsung is making what you want. (Afair)
Yes, you can pair two Bluetooth devices at a time but only one can be used/selected for calling. If you want to pair two Devices of this type you have to disable Media or Calling for the first connected devices. Then the other one is connecting fine.
I use this in my car. Bluetooth streams music to a FM Transmitter and is connected to my car for calls. In this case (when one device is detected as media only) you can connect the Calling devices without a flaw.

Wired AndroidAuto and sending audio through Bluetooth

I recently installed an after market AndroidAuto unit in my car, it is only available as a wired connection, which is fine. When I plug my device, the sound is routed through the USB (and from there to the unit's AUX interface) which sounds crappy.
My car's bluetooth stereo sounds much much better.
According to Google's site and some other sources, it is not possible to re-route the audio through Bluetooth.
Is there some kind of mod or an application (combined with root) that can actually work around this limitation?
